The three major and most common types of cylinder configurations can be distinguished into ram-style, tie rod and welded cylinders.
As understood by the name, ram cylinders are utilized in heavy-duty applications. They are involved in pulling the load rather than pushing the load.
The tie-rods are typically situated on the outside housing of the cylinder to provide an extra stability.
The welding flange construction cylinder has end flanges that are welded onto the barrel and an end cap is attached with each flange. The end cap is secured in its place by bolts which slip through the holes in each of the end cap and thread into tapped holes in every end flange. This structure is more compact and lighter than the regular tie-rod configuration, and this explains why the welded cylinder finds wide application in varied mobile equipments.
A variant to this creation comprises each end cap that is threaded into the ending of the barrels. This construction, on the other hand, usually cannot hold as much of high pressure rating as held by welded cylinders and they are also more difficult to reassemble and disassemble.
There are many hydraulic cylinder manufacturers that manufacture a huge variety of hydraulic cylinders like trunions, telescopic and clevis etc.
Essem Engineers are known to be a huge name in the world of hydraulic cylinder manufacturers. The welding flange construction cylinders offered by them are without doubt flawless and work for long durations without any damage. As a result no repairing and servicing is required for a long time.
